<li>安装一定要在自己的目录下进行，以免更改他人环境 </li>
<li>在安装之前配置清华镜像，下载速度会很快，更换下载源的方法如 下: 在自己的目录下新建一个.pip 文件夹，在.pip 文件夹下新建 pip.conf 文件，内容为：<br>[global] index-url = <a target="_blank" rel="noopener external nofollow noreferrer" href="https://pypi.douban.com/simple/">https://pypi.douban.com/simple/</a><br>[install] trusted-host = <a target="_blank" rel="noopener external nofollow noreferrer" href="https://pypi.douban.com/simple/">https://pypi.douban.com/simple/</a><br>几个常用的国内源，大家可以自己选择，替换文件中的网址就可以：<br>阿里云 <a target="_blank" rel="noopener external nofollow noreferrer" href="http://mirrors.aliyun.com/pypi/simple/">http://mirrors.aliyun.com/pypi/simple/</a> 中国科技大学 <a target="_blank" rel="noopener external nofollow noreferrer" href="https://pypi.mirrors.ustc.edu.cn/simple/">https://pypi.mirrors.ustc.edu.cn/simple/</a><br>豆瓣(douban) <a target="_blank" rel="noopener external nofollow noreferrer" href="http://pypi.douban.com/simple/">http://pypi.douban.com/simple/</a> 清华大学 <a target="_blank" rel="noopener external nofollow noreferrer" href="https://pypi.tuna.tsinghua.edu.cn/simple/">https://pypi.tuna.tsinghua.edu.cn/simple/</a><br>中国科学技术大学 <a target="_blank" rel="noopener external nofollow noreferrer" href="http://pypi.mirrors.ustc.edu.cn/simple/">http://pypi.mirrors.ustc.edu.cn/simple/</a> </li>

<li>实验室的cuda和cudnn一般都是配置好的，直接引用即可。避免重复下载，浪费空间。</li>
<li>跑程序时，加上 os.environ[“CUDA_VISIBLE_DEVICES”]=”0”,0 是 GPU 标志，更换数字即更换 GPU </li>
<li>注意区分命令前有无 sudo 的区别，sudo为增加权限使用。 </li>
<li>升级pip：pip install –upgrade pip</li>
